Effective Modern CMake

Getting Started

For a brief user-level introduction to CMake, watch C++ Weekly, Episode 78, Intro to CMake by Jason Turner. LLVM’s CMake Primer provides a good high-level introduction to the CMake syntax. Go read it now.

After that, watch Mathieu Ropert’s CppCon 2017 talk Using Modern CMake Patterns to Enforce a Good Modular Design (slides). It provides a thorough explanation of what modern CMake is and why it is so much better than “old school” CMake. The modular design ideas in this talk are based on the book [Large-Scale C++ Software Design](https://www.amazon.de/Large-Scale-Soft

101 Rx Samples in C#

This was taken from http://rxwiki.wikidot.com/101samples, because I wanted to be able to read it more comfortable with syntax highlighting.

Here's the unedited original, translated to Github Markdown glory:

	// Shinobi (http://shinobi.video) - FFMPEG H.264 over HTTP Test
	// How to Use raw H.264 (Simulated RTSP)
	// 1. Start with `node ffmpegToWeb.js`
	// 2. Get the IP address of the computer where you did step 1. Example : 127.0.0.1
	// 3. Open VLC and "Open Network Stream".
	// 4. Input the following without quotes : `http://127.0.0.1:8001/h264` and start.

	var io = require('socket.io');
	var events = require('events');

	// requires Jint
	//
	// this can be used for video streams as well, with few modifications

	ZigZag-Encoding
	---------------

	Maps negative values to positive values while going back and
	forth (0 = 0, -1 = 1, 1 = 2, -2 = 3, 2 = 4, -3 = 5, 3 = 6 ...)

	(i >> bitlength-1) ^ (i << 1)

	with "i" being the number to be encoded, "^" being
	XOR-operation and ">>" would be arithemtic shifting-operation
